Manufacturing Facility $2-$ Improved

Enginecring has applied $6$ Sigma and Lean Manufacturing techniques and has been able to reduce the setup time on Machine $1$ for part A and part B to $1$ minute. The demand for the facility has not increased. It is still $600$ assemblies per week $(15$ assemblies$/$hour$).$ The manufacturing facility is available for $8$ hours per day, $5$ days per weck.

Deliverable Set $2$:

For manufacturing facility $2,$ answer the following questions. To reccive credit, clearly explain your logic and show all your work.

Assuming $100\%$ uptime and availability, identify the optimum batch sizes to be processed in Machine $1,$ Machine $2,$ and assembly while still meeting the $600$ assembly$/$week production requirements.

What is the bottleneck in the manufacturing facility? Justify your choice.

The part $C$ raw material buffer, the Part $C$ component buffer, and the part A and part $B$ component buffers have been removed from the system. Why are they not necessary?

In dollars, what is the average amount of work$-$in$-$progress, WIP, inventory?

What is the approximate lead time of an assembly, assuming that no time is required to move the materials and no time is lost due to machines$/$assembly waiting for parts?
